SPACE WEATHER

http://spaceweather.frederick.ac.cy/

  • The term “space weather” describes various changes that occur in our Sun and affect the flow and velocity of solar wind, the magnetosphere, the ionosphere and the Earth’s thermosphere. The ionosphere is the area of ​​the atmosphere from about 60 to 1000 kilometers above the Earth’s surface where solar radiation causes ionization of its constituents, that is, it charges very small particles that receive electric charge, becoming ions.
  • These phenomena affect the performance and durability of a wide variety of man-made technological systems in both space and earth environments that can endanger human health and safety.
  • Space weather demonstrates its own climate, which varies from one day (the time the Earth rotates around its axis) to 11 years (the time between two peaks of solar activity) or even more.
  • Although there is an association with astrophysical phenomena outside our solar system, the main source of space weather is the sun.
  • Schematically we would write that a Solar or Geomagnetic Storm results from the interaction of large amounts of charged particles fired by explosions into the sun (plasma) with the earth’s magnetic field.
